Abstract: Methods and image processing devices for encoding and decoding private data are proposed. The method for encoding private data includes to receive an original video frame, mask at least one private area in the original video frame to generate a protected video frame, generate a first encoded frame by encoding the protected video frame, and generate at least one output bitstream for streaming or storage according to the first encoded frame. The method for decoding private data includes to receive at least one input video bitstream to obtain a first encoded bitstream and a second encoded bitstream, decode the first encoded bitstream to generate a protected video frame including image data associated with at least one private area, and output the protected video frame to a display queue such that the at least one private area is displayed.

Abstract: A method for a video encoder includes steps of: receiving a series of input frames; performing at least one of intra-prediction and inter-prediction on the series of input frames for generating at least one of an intra frame (I-frame), a predictive frame (P-frame), and a key predictive frame (key P-frame); generating an encoded bitstream with respect to a first input frame determined as the I-frame among the series of input frames; and performing inter-prediction on a second input frame determined as a key P-frame among the series of input frames according to a first reference frame which is derived from the encoded bitstream with respect to the first input frame.

Abstract: A video encoding apparatus and an operating method thereof are provided. The video encoding apparatus includes an encoding circuit, a reconstructed frame generating circuit, a deblocking filter and a determination circuit. The encoding circuit generates encoded data according to a residual frame and generates a reconstructed residual frame. The reconstructed frame generating circuit generates a first reconstructed frame according to the reconstructed residual frame and a predicted frame. The deblocking filter generates a second reconstructed frame by eliminating discontinuities in reconstructed blocks of the first reconstructed frame. The current reconstructed block is not output to the memory when a current reconstructed block is identical to a co-located reference block of a reference frame stored in the memory. The current reconstructed block is output to the memory when the current reconstructed block is different from the co-located reference block in the reference frame.
